17. Kraftwerk, 'Trans Europe Express'

It was recorded in 1977, but this cornerstone of both hip-hop and EDM still sounds like the future – as imagined by a bunch of well-groomed Germans chilling in an Amsterdam hash bar. "Europe Endless" conjures a procession of chrome-plated cyber-gnomes, "Showroom Dummies" sounds like a wake 'n' bake trip to the Berlin’s KaDeWe superstore. But the title track, which informed Afrika Bambaataa's "Planet Rock" and a generation of breakdancers, is like sneaking vaporizer one-hits on the Acela train en route to . . . damn yo, what's our stop again?
